=head1 NAME

Test::Specio - Test helpers for Specio

=head1 VERSION

version 0.46

=head1 SYNOPSIS

use Test::Specio qw( test_constraint :vars );

test_constraint(
      t('Foo'), {
          accept => [ 'foo', 'bar' ],
          reject => [ 42,    {}, $EMPTY_STRING, $HASH_REF ],
      }
  );

=head1 DESCRIPTION

This package provides some helper functions and variables for testing Specio
types.

=head1 EXPORTS

This module provides the following exports:

=head2 test_constraint( $type, $tests, [ $describer ] )

This subroutine accepts two arguments. The first should be a Specio type
object. The second is hashref which can contain the keys C<accept> and
C<reject>. Each key should contain an arrayref of values which the type
accepts or rejects.

The third argument is optional. This is a sub reference which will be called
to generate a description of the value being tested. This defaults to calling
this package's C<describe> sub, but you can provide your own.

=head2 describe($value)

Given a value, this subroutine returns a string describing that value in a
useful way for test output. It know about the various classes used for the
variables exported by this package and will do something intelligent when such
a variable.

=head2 builtins_tests( $GLOB, $GLOB_OVERLOAD, $GLOB_OVERLOAD_FH )

This subroutine returns a hashref containing test variables for all builtin
types. The hashref has a form like this:

{
      Bool => {
          accept => [
              $ZERO,
              $ONE,
              $BOOL_OVERLOAD_TRUE,
              $BOOL_OVERLOAD_FALSE,
              ...,
          ],
          reject => [
              $INT,
              $NEG_INT,
              $NUM,
              $NEG_NUM,
              ...,
              $OBJECT,
          ],
      },
      Maybe => {...},
  }

You need to pass in a glob, an object which overloads globification, and an
object which overloads globification to return an open filehandle. See below
for more details on how to create these things.

=head2 Variables

This module also exports many variables containing values which are useful for
testing constraints. Note that references are always empty unless stated
otherwise. You can import these variables individually or import all of them
with the C<:vars> import tag.

=head2 Globs and the _T::GlobOverload package

To create a glob you can pass around for tests, use this code:

my $GLOB = do {
      no warnings 'once';
      *SOME_GLOB;
  };

The C<_T::GlobOverload> package is defined when you load C<Test::Specio> so
you can create your own glob overloading objects. Such objects cannot be
exported because the glob they return does not transfer across packages
properly.

You can create such a variable like this:

local *FOO;
  my $GLOB_OVERLOAD = _T::GlobOverload->new( \*FOO );

If you want to create a glob overloading object that returns a filehandle, do
this:

local *BAR;
  open BAR, '<', $^X or die "Could not open $^X for the test";
  my $GLOB_OVERLOAD_FH = _T::GlobOverload->new( \*BAR );
